Scatter of labels between repeated observations. The S/N_r is defined as the average value of the S/N in the r band of the observations, and the scatter Δ_repl is the standard deviation of the labels in the units applicable to the respective labels, weighted by their S/N. Dashed orange lines represent the median value of the scatter in each S/N bin. Horizontal red lines indicate the median value of Δ_repl from the entire sample with repeated observations, which are also marked in the top-right corner.
